The change stage of a user program is shared, and the suspension time of a device caused by updating the user program is shortened. A controller includes a first storage unit, a first change management unit, and a first user program generation unit. The first storage unit stores a data container. When the data container stored in the first storage unit is changed, the first change management unit stores a change record of the data container into a first update history. The first change management unit stores a new data container generated using the change record into the first storage unit. The first user program generation unit generates a user program using a user program resource contained in the new data container.

Controller and control system

Provided is a support device that supports easier data exchange between PLCs without relying on a type of a PLC of the other communication party. The support device includes: a first input unit for receiving information defining, on a data-by-data basis, variables for data handled by the first programmable logic controller; a second input unit for receiving a source program expressing processing executed on the first programmable logic controller using the defined variables; a third input unit for receiving information that identifies a type of a second programmable logic controller in association with a first variable; and a generation unit that generates the executable program using the information defining the variables and the source program. The generation unit adapts a data structure of first data secured in the memory in correspondence with the first variable in accordance with the type of the second programmable logic controller.
